IMPROVEMENT IN COLLAR AND SLEEVE BUTTONS.

Specification forming part of Letters Patent No. 210,017, dated November19, 1878; application led July 27, 1878.

To all whom it may concern:

Be it known that I, WELLINGTON P. Dor.- LOFF, of Providence, State ofRhode Island, have invented a new and valuable Improvement in Collar andSleeve Buttons; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and iigures of reference markedthereon.

Figure 1 of the drawings is a representation of a central longitudinalsection of my improved button. Figs. 2, 3, and 4 are details.

This invention has relation to improvements in collar and sleevebuttons; and the nature of the invention consists in certain novelcombinations of parts, whereby a sectional button of exceptionalexcellence is produced, as will be hereinafter more fully set forth.

In the annexed drawings, the letter A indicates the face of the button,having a tubular post, a, of suitable dimensions. Within' this post isrigidly secured a forked spring-griper, composed of two arms, i i,united preferably at their inner ends, and terminating at their freeends in angular jaws c.' These arms extend nearly to the end of post a,and are allowed to separate, under circumstances hereinafter set forth,by the chambers b at opposite sides of the post. These chambers and postform together a body of oblong form, and, being introduced into abutton-hole, serve to prevent the button from turning, thus when aiigure is used on the face-plate keeping it upright instead of sidewiseor upside down.

groove, g. From this groove the post gradu` ally thickens up to a pointabout midway of its length, when it tapers offto a rounded end,

h. AThis post, inputting the parts of the button together, is thrustinto post a between the arms 'i of the griper, causing them tokgradually separate until the angular' jaws c drop into the groove g,when the reaction of the said arms causes the jaws to bind upon the postb in the groove aforesaid, requiring considerable'force to separatethem. This force, however, being applied, the swell s of the solid postcauses the arms t to separate, and allows the parts of the button to bedisconnected.

What I claim -as new, and desire to secure by Letters Patent, is-

In a sectional collar or sleeve button, the combination, with a backplate, A, having tubular post a and recesses b', and the springgriper t'11, havingangular jaws c, inside of said post, of a faceplate, B, havingsolid post b,

provided with a groove, g, near its base, a swell, s, outside of saidgroove, and a rounded tapering end, h, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
